Last few days I was flying close to some military areas close to Turkish border with Syria, getting all sorts of GPS errors form NO POSITION to different inconsistencies and funny wind data. Pictures below show some examples, reverting to old school IFR and flying to VOR and estimating wind correction was the only possibility for navigation.
Is the last one saying both “NO GPS POSITION” and “INTEG OK”?
He’s got a 2D fix which is fine for Nav but there isn’t a 3D for the terrain database, hence the NO GPS POSITION annunciation on the terrain inset.
I also got complete loss of GPS including 2D fix but was occupied with flying and didn’t take that picture.
On a recent multi-day trip around the SW US I had GPS loss on almost every leg. Lasted for around 30 to 60 seconds then came back. We’re still trying to figure out if that was/is an installation issue or if it was jamming. There’s a blanket NOTAM out covering pretty much all of the western US about intermittent GPS signal jamming.

You do have a complete loss of GPS in some of the pictures — that’s part of what “DR” means.
You don‘t have to fly Turkey, GPS jammed areas are all over Europe. Just yesterday it surprised me again VFR in The Netherlands, until I remembered – ah, that area always has none GPS. But, they do have sufficient fast roads to serve as guidance.

Can you be more specific?

Where was this, specifically?
What do you fly, Markuus? It does an awful lot of hours so you must visit a lot of places. With that many hours, navigating by

must require a very high degree of skill.
Usually the random GPS-jammed areas are in the vicinity of some military installations or routes.
Yesterdays deja vu was the famous EHGR-EHRD-EHTL-EHVK area, currently also RAT‘ed.
